Or people like what they like. Imagine that.
Most species have some selectivity used for determining mates, as well as reproductive strategies.
There is no shame in having a relationship with someone you find physically and mentally attractive.
After all, if children are the biggest investment in your life, may as well have them with someone you love.
Most western heterosexual women prefer men that are tall and have good facial symmetry. My gay friend told me he likes lumberjack types with heavy musculature. I personally prefer a taller woman with a good hip to waist ratio.
I wouldn't shame a woman for liking what she likes, nor would I shame my friend for his preferences. Nor should Cis hetero men be shamed for what they like. It is an individual decision.
There is a great deal more to relationship success beyond mere attractiveness. But, it has to start somewhere.
